.Applie-.aimr mea Marcil 3c, 19e-5. serial No; regain The present invention relates :to reflectors,

such as are used by photographers for rcflecting light tol obj ectswhen photographed,-

and theinvention aiiiiswtoprovide a novel` ment to differentl angular positions initsv different vertical adjustments, in orderI that the light reflected by the mirror maybe diirected in the desi-red directionto an object.

A still further object of the invention is to provide novel means for pivotally andv slide-bly connectingfaiinirror or similar: member with a standor other support', and forn'iaintaining theJ inirror or member in its` different adjustments. l

l/Vitli` the foregoing. and other objects in view, which willA be apparent asthe descrip tion proceeds,ithe invention resides in the construction and arrangement of' parts, hereinafter described` and claimed,- it being.

understood that changes can be'made with-iii` the scope of what isclaimed, without depart'- ingfroin the spirit of) the invention- The invention is illustrated inthe accom-y panying drawing, wherein- Figure 1 is a" perspective view of the' refleotoi' with the mirror in its highest? position and the smallinirror surface disposedy forwardly'.

Fig. 2 is a perspective view of the device showing the mirror in its lowerinost position and"4 the large mirror surface dispose-df forwardly.

In carrying out the invention there isV provided a stand or support including a suitable base 71 preferably mounted on casters 8 so that the stand may be conveniently moved about on the floor,A and the stand ining movement about horizontal axis atl cludes a' pair ofy standards or posts' 9 rising` vertical-ly from the. base to a suitable heightfand spaced apart parallel with one another. Thesta-ndfmay be` constructed of wood orfmetal, andfthe standardsfor barsftl support the mirror or reflecting meniber` 10 which is mounted `between saidlstandards.

The mirror 10 iso-fsuitable sizefandfcomprises4 a frame 11 having a panell thereinv provided with a large mirror surface 12 at one side and: a smally mirror surface 135 at theoppo'site side, the field or space 14e between the surface lil-and frame 1'1y beingiof dull or non-reflecting nature. The opposite` mirror surfaces may be brought into 'playa by reversing the mirror in order that; eithc-nr.` broad or narrow beams offliglit:` may4 bel ref flected.

The mirror4 or ineinberf 10 is `inountedr for sliding and pivotal movements in" the stand:

For this purpose, a slideE 1'5 ismovable on each standard orbarA QaiidaispivotallyconL nect'edf with a pla-te 16 secured tothe oor; responding side edge of the frame 11 by screws 17 ori otherwise; Each"y slide,` 15` is"v bent from a l` bar, orf strip into' rectangulary loop shapefso'as to'passY over the-standard 9, an'dfwitlrtheterminalsf of the stripover-y lapped, as at 18, adjacent to the plate 16:- A

pivot bolt 19 engagesy through apertures iii the .terminalsv 18 and' plate 16 for pivotally' connecting the inner portion; of the slide with( the plate 16' and; framellf. The' head 2O of the bolt is' located within* the-slide15' between the standardi 9 and terminals 1S,

and nuts 211 are screw-threaded on the' boit and-are located within. ai recess or cavity 22 providedV the edge portion ofi-f the frame 1.1, oneof` said nuts serving'. as a lock nutrfor the other toprevent thebolt from loosening; The mirrorror member 10foan therefore movefwitlr the lslides 15 alongt'he stand'- ards oribar-s 9", audit-hemir-rorfniayy alsorbe rotated' orturnedL about? the' horizontal axis of the' pivot bolts 19 at th-e opposite sides.l In order tocreate friction for maintainingthe adjustment ofi the mirror, a doubleor bowed leaf spring 23 isdisposed within"l each slidewith its terminals bearingI against the inner# side of the corresponding standard' 9, and the intermediate portion-of the spring engages thebolt 19.' The spring: is under pressure between the slide 15 and standard 9 toy create sufficient friction topre-vent the mirror from sliding on the 'standl accidentally, although the mirror may be moved" up` and down easily by hand. Furthermore, the intermediate portion of the spring has a reverse bowed portion 25, as seen in Fig. 5, which is straightened out` against the inner portion of the slide 15 when the bolt 19 is tightened, and the tension obtained will hold the plate 16 and slide 15 together under spring pressure, so that friction is suflicient to prevent the mirror 10 from turning accidentally on its pivots, but permitting the mirror to be turned conveniently by hand to different angular positions. The single spring at each side therefore supplies the friction to prevent both the accidental sliding and turning movements of the mirror when adjusted to a desired position. Spring washers 24 are also disposed on each bolt 19, one between the slide 15 and head of the bolt and the other between the plate 16 and nuts 21, which in being under pressure when the bolt is tightened will assist the spring 23 in creating friction between the slide 15 and plate 16.

Each slide 15 has an aperture 26 at its outer portion through which a screw-driver may be inserted, when the mirror 10 is removed from the stand, in order that the bolt 19 may be rotated for separating or assembling the parts. It is apparent that the upper end of the stand being open, with the upper ends of the standards or bars 9 disconnected,will permit the mirror and slide 15 to be removed upwardly from the stand. "When the mirror is removed from thestand, the bolts 19 may be rotated by inserting a screw-driver or other implement through the apertures 26, so as to regulate the friction between the slides and mirror.

Both sides of the stand are alike, so that the stand may be turned aroundor reversed side for side, and the stand'may also be moved about conveniently on the floor to the desired position as well as being turned about a vertical axis. The mirror is readily slid upwardly and downwardly to the desired height, and the mirror is also readily reversed so that either the large mirror surface 12 or the small mirror surface 13 may be brought into position for reiiecting the light. The mirror may be located higher up than the object for reiiecting the light downwardly atan angle, or may be located lower down to' reflect the light upwardly at an angle. A wide latitude of adjustment is therefore permitted to reflect the light, either in a large or small beam, at different angles and elevations.

The device is intended especially for use by photographers, but the improvements may be used for other appropriate purposes also. Having thus described the invention, what is claimed as new is 1. In a device of the character described, a bar, a slide movable on said bar, a reflecting member pivotally connected with said slide, and a spring having a yieldable portion between the slide and bar for creat-- ing friction between them, and having another independently yieldable portion arranged to yield and create friction between kthe slide and reflecting member.

2. In a device of the character described, a bar, a slide movable on the bar, a reflecting member, a pivot element connecting said member and slide, and a spring having a yieldable portion disposed between the slide and bar for creating. friction between them, and having an independently yieldable portion engaging said pivot element to yield and provide friction between the slide and reflecting member.

3. In a device of the character described,

a bar, a slide movable thereon, a reflecting member, a pivot element connecting said member and slide, and a leaf spring having a terminal portion between the slide and bar for creating friction between them, and having another independently yieldable portion engaging said pivot element to yield and create friction between the slide and reflecting member.

l 4, In a device of the character described, a bar, a slide movable on the bar, a reflecting member, a pivot element connecting said member and slide, and a bowed leaf spring having its intermediate portion engaging said pivotl element within the slide and its terminals bearing against said bar to create friction between the bar and slide, the intermediate portion of said spring having independently yieldable means to create friction between said member and slide.

5. A device of the character described comprising parallel bars, slides movable thereon, a` reflecting member between said bars, pivot elements connecting said member and slides, and bowed leaf springs having their intermediate portions secured by said elements and having their terminals bearing against said bars, said springs having yieldable portions yieldable independently of the terminals of the springs and arranged to be flexed to create friction between said slides and member.

6. A. device of the character described comprising parallel bars, slides surrounding and movable on said bars, a reflecting member between said slides, pivotbolts connectying said member and slides, and bowed leaf springs having their intermediate portions secured by said elements within said slides and having their terminals bearing against said bars, said leaf springs having said intermediate portions thereof bowed reversely, and straightened out when said pivot elements are tightened so as to create friction between said slides and member.
